v, Sx, n
Summary statistics (mean, standard deviation, and sample size)
for the one-sample tests and intervals.
s1
The known population standard deviation from the first population
for the two-sample tests and intervals. Must be a real number > 0.
s2
The known population standard deviation from the second
population for the two-sample tests and intervals. Must be a real
number > 0.
List1, List2 The names of the lists containing the data you are testing for the
two-sample tests and intervals. Defaults are L1 and L2,
respectively.
Freq1, Freq2 The names of the lists containing the frequencies for the data in
List1 and List2 for the two-sample tests and intervals.
Defaults=1. All elements must be integers
| 0.
v1, Sx1, n1, v2, Sx2, n2
Summary statistics (mean, standard deviation, and sample size)
for sample one and sample two in the two-sample tests and
intervals.
Pooled Specifies whether variances are to be pooled for 2-SampTTest
and 2-SampTInt. No instructs the TI-84 Plus not to pool the
